The 1970s witnessed an outpouring of research on the Andean cultural tradition sufficient to place Andean studies among the well-established regional subspecialties of anthropology. Among the historic factors converging to produce this abundance was the emergence of a generation of fieldworkers trained by ethnohistorians such as John Murra, John Rowe, Herman Trimborn, and R. T. Zuidema. Their understanding of historical and intellectual activity in past Andean communities made it possible, even in the heyday of development theories, to appreciate the modern Andean tradition as an active and creative rather than merely resistant presence. At the same time, events within the Andean republics called forth new interest in the indigenous tradition. In Peru the Velasco regime (1968–75), with its far-reaching intervention into rural institutions, received both support and criticism from those whose knowledge of the Quechua countryside seemed suddenly valuable. In Ecuador the post-1974 oil boom awakened hope for a more “integrated” national state, thereby provoking debate (as yet inconclusive) between pluralist and assimilationist approaches to the problems of the multiethnic highlands. In all the Andean countries regional and national research institutions with periodicals and monographs of their own took form. Generally outside universities, and sometimes with support from sectors of the Catholic Church increasingly open to the study of local belief, they produced distinctive schools of thought fruitfully different from the academic tradition proper. Regional meetings such as the Congresos del Hombre Andino indicated the coalescence of an Andean field of study across national boundaries. In some places, self-mobilization of Andean communities and experimentation with bilingual media and institutions raised hopes for a definition of the Andean situation from the Andean side, a definition not precast in terms familiar to the Hispanic-oriented outsider.
